When installing jar to the repository - Is it possible to tell maven to add artifact descriptor file (something specific for my needs) alongside the jar file?
So in the repository I will have:
What you are looking for is a "classifer". Both source JAR files and site zip files are often loaded into repositories as classifiers. What you need is to either find or write a plugin that will let you identify the descriptor as a classifier, and that will attach that classifier to the build. Looks like the Build Helper plugin might just do this for you (see the Usage page for an example):
